*
* Version 0.1.10
*
* The ANSI C standard committee, for the C99 standard, specified the
* inclusion of a new standard include file called stdint.h. This is
* a very useful and long desired include file which contains several
* very precise definitions for integer scalar types that is
* critically important for making portable several classes of
* applications including cryptography, hashing, variable length
* integer libraries and so on. But for most developers its likely
* useful just for programming sanity.
*
* The problem is that most compiler vendors have decided not to
* implement the C99 standard, and the next C++ language standard
* (which has a lot more mindshare these days) will be a long time in
* coming and its unknown whether or not it will include stdint.h or
* how much adoption it will have. Either way, it will be a long time
* before all compilers come with a stdint.h and it also does nothing
* for the extremely large number of compilers available today which
* do not include this file, or anything comparable to it.
*
* So that's what this file is all about. Its an attempt to build a
* single universal include file that works on as many platforms as
* possible to deliver what stdint.h is supposed to. A few things
* that should be noted about this file:
*
* 1) It is not guaranteed to be portable and/or present an identical
* interface on all platforms. The extreme variability of the
* ANSI C standard makes this an impossibility right from the
* very get go. Its really only meant to be useful for the vast
* majority of platforms that possess the capability of
* implementing usefully and precisely defined, standard sized
* integer scalars. Systems which are not intrinsically 2s
* complement may produce invalid constants.
*
* 2) There is an unavoidable use of non-reserved symbols.
*
* 3) Other standard include files are invoked.
*
* 4) This file may come in conflict with future platforms that do
* include stdint.h. The hope is that one or the other can be
* used with no real difference.
*
* 5) In the current verison, if your platform can't represent
* int32_t, int16_t and int8_t, it just dumps out with a compiler
* error.
*
* 6) 64 bit integers may or may not be defined. Test for their
* presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
* Note that this is different from the C99 specification which
* requires the existence of 64 bit support in the compiler. If
* this is not defined for your platform, yet it is capable of
* dealing with 64 bits then it is because this file has not yet
* been extended to cover all of your system's capabilities.
*
* 7) (u)intptr_t may or may not be defined. Test for its presence
* with the test: #ifdef PTRDIFF_MAX. If this is not defined
* for your platform, then it is because this file has not yet
* been extended to cover all of your system's capabilities, not
* because its optional.
*
* 8) The following might not been defined even if your platform is
* capable of defining it:
*
* WCHAR_MIN
* WCHAR_MAX
* (u)int64_t
* PTRDIFF_MIN
* PTRDIFF_MAX
* (u)intptr_t
*
* 9) The following have not been defined:
*
* WINT_MIN
* WINT_MAX
*
* 10) The criteria for defining (u)int_least(*)_t isn't clear,
* except for systems which don't have a type that precisely
* defined 8, 16, or 32 bit types (which this include file does
* not support anyways). Default definitions have been given.
*
* 11) The criteria for defining (u)int_fast(*)_t isn't something I
* would trust to any particular compiler vendor or the ANSI C
* committee. It is well known that "compatible systems" are
* commonly created that have very different performance
* characteristics from the systems they are compatible with,
* especially those whose vendors make both the compiler and the
* system. Default definitions have been given, but its strongly
* recommended that users never use these definitions for any
* reason (they do *NOT* deliver any serious guarantee of
* improved performance -- not in this file, nor any vendor's
* stdint.h).
*
* 12) The following macros:
*
* PRINTF_INTMAX_MODIFIER
* PRINTF_INT64_MODIFIER
* PRINTF_INT32_MODIFIER
* PRINTF_INT16_MODIFIER
* PRINTF_LEAST64_MODIFIER
* PRINTF_LEAST32_MODIFIER
* PRINTF_LEAST16_MODIFIER
* PRINTF_INTPTR_MODIFIER
*
* are strings which have been defined as the modifiers required
* for the "d", "u" and "x" printf formats to correctly output
* (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
* (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
* PRINTF_INTPTR_MODIFIER is not defined for some systems which
* provide their own stdint.h. PRINTF_INT64_MODIFIER is not
* defined if INT64_MAX is not defined. These are an extension
* beyond what C99 specifies must be in stdint.h.
*
* In addition, the following macros are defined:
*
* PRINTF_INTMAX_HEX_WIDTH
* PRINTF_INT64_HEX_WIDTH
* PRINTF_INT32_HEX_WIDTH
* PRINTF_INT16_HEX_WIDTH
* PRINTF_INT8_HEX_WIDTH
* PRINTF_INTMAX_DEC_WIDTH
* PRINTF_INT64_DEC_WIDTH
* PRINTF_INT32_DEC_WIDTH
* PRINTF_INT16_DEC_WIDTH
* PRINTF_INT8_DEC_WIDTH
*
* Which specifies the maximum number of characters required to
* print the number of that type in either hexadecimal or decimal.
* These are an extension beyond what C99 specifies must be in
* stdint.h.
*
* Compilers tested (all with 0 warnings at their highest respective
* settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
* bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
* .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
*
* This file should be considered a work in progress. Suggestions for
* improvements, especially those which increase coverage are strongly
* encouraged.
*
* Acknowledgements
*
* The following people have made significant contributions to the
* development and testing of this file:

* Chris Howie
* John Steele Scott
* Dave Thorup

* 'preprocessing' flags is useful if the input scene does not conform to
* Assimp's default conventions as specified in the @link data Data Structures Page @endlink.
* In short, this means the geometry data should use a right-handed coordinate systems, face
* winding should be counter-clockwise and the UV coordinate origin is assumed to be in
* the upper left. The #aiProcess_MakeLeftHanded, #aiProcess_FlipUVs and
* #aiProcess_FlipWindingOrder flags are used in the import side to allow users
* to have those defaults automatically adapted to their conventions. Specifying those flags
* for exporting has the opposite effect, respectively. Some other of the
* #aiPostProcessSteps enumerated values may be useful as well, but you'll need
* to try out what their effect on the exported file is. Many formats impose
* their own restrictions on the structure of the geometry stored therein,
* so some preprocessing may have little or no effect at all, or may be
* redundant as exporters would apply them anyhow. A good example
* is triangulation - whilst you can enforce it by specifying
* the #aiProcess_Triangulate flag, most export formats support only
* triangulate data so they would run the step even if it wasn't requested.
*
* If assimp detects that the input scene was directly taken from the importer side of
* the library (i.e. not copied using aiCopyScene and potetially modified afterwards),
* any postprocessing steps already applied to the scene will not be applied again, unless
* they show non-idempotent behaviour (#aiProcess_MakeLeftHanded, #aiProcess_FlipUVs and

/** Helper structure to describe a virtual camera.
*
* Cameras have a representation in the node graph and can be animated.
* An important aspect is that the camera itself is also part of the
* scenegraph. This means, any values such as the look-at vector are not
* *absolute*, they're <b>relative</b> to the coordinate system defined
* by the node which corresponds to the camera. This allows for camera
* animations. For static cameras parameters like the 'look-at' or 'up' vectors
* are usually specified directly in aiCamera, but beware, they could also
* be encoded in the node transformation. The following (pseudo)code sample
* shows how to do it: <br><br>
* @code
* // Get the camera matrix for a camera at a specific time
* // if the node hierarchy for the camera does not contain
* // at least one animated node this is a static computation
* get-camera-matrix (node sceneRoot, camera cam) : matrix
* {
* node cnd = find-node-for-camera(cam)
* matrix cmt = identity()
*
* // as usual - get the absolute camera transformation for this frame
* for each node nd in hierarchy from sceneRoot to cnd
* matrix cur
* if (is-animated(nd))
* cur = eval-animation(nd)
* else cur = nd->mTransformation;
* cmt = mult-matrices( cmt, cur )
* end for
*
* // now multiply with the camera's own local transform
* cam = mult-matrices (cam, get-camera-matrix(cmt) )
* }
* @endcode
*
* @note some file formats (such as 3DS, ASE) export a "target point" -
* the point the camera is looking at (it can even be animated). Assimp
* writes the target point as a subnode of the camera's main node,
* called "<camName>.Target". However this is just additional information
* then the transformation tracks of the camera main node make the
* camera already look in the right direction.

* #aiProcess_FlipWindingOrder flags are used in the import side to allow users
* to have those defaults automatically adapted to their conventions. Specifying those flags
* for exporting has the opposite effect, respectively. Some other of the
* #aiPostProcessSteps enumerated values may be useful as well, but you'll need
* to try out what their effect on the exported file is. Many formats impose
* their own restrictions on the structure of the geometry stored therein,
* so some preprocessing may have little or no effect at all, or may be
* redundant as exporters would apply them anyhow. A good example
* is triangulation - whilst you can enforce it by specifying
* the #aiProcess_Triangulate flag, most export formats support only
* triangulate data so they would run the step anyway.
*
* If assimp detects that the input scene was directly taken from the importer side of
* the library (i.e. not copied using aiCopyScene and potetially modified afterwards),
* any postprocessing steps already applied to the scene will not be applied again, unless
* they show non-idempotent behaviour (#aiProcess_MakeLeftHanded, #aiProcess_FlipUVs and

* <li>Specify the #aiProcess_FindDegenerates flag.
* </li>
* <li>Set the <tt>#AI_CONFIG_PP_FD_REMOVE</tt> importer property to
* 1. This will cause the step to remove degenerate triangles from the
* import as soon as they're detected. They won't pass any further
* pipeline steps.
* </li>
* </ul>
* <br><b>2.</b>(if you don't support lines and points at all)</br>
* <ul>
* <li>Specify the #aiProcess_FindDegenerates flag.
* </li>
* <li>Specify the #aiProcess_SortByPType flag. This moves line and
* point primitives to separate meshes.
* </li>
* <li>Set the <tt>#AI_CONFIG_PP_SBP_REMOVE</tt> importer property to
* @code aiPrimitiveType_POINTS | aiPrimitiveType_LINES
* @endcode to cause SortByPType to reject point
* and line meshes from the scene.
* </li>
* </ul>
* @note Degenerate polygons are not necessarily evil and that's why
* they're not removed by default. There are several file formats which
* don't support lines or points, and some exporters bypass the
